Which of the following statistical methods should you use. Question is at top of page
You wish to test the following claim (H.) at a significance level of a = 0.002. H.:p1 – P2 = 0 P2 > 0 You obtain a sample from the first population with 384 successes and 63 failures. You obtain a sample from the second population with 606 successes and 116 failures. What is the test statistic for this sample? (Report answer accurate to three decimal places.) test statistic = What is the p-value for this sample? (Report answer accurate to four decimal places.) p-value = %3D The p-value is... O less than (or equal to) a greater than a This test statistic leads to a decision to... reject the null hypothesis accept the null hypothesis fail to reject the null hypothesis As such, the final conclusion is that...

Consider a completely randomized design with five treatments: A, B, C, D, and E. The ANOVA F-test revealed significant differences among the means. A multiple-comparison procedure was used to compare all possible pairs of treatment means at a = .05. The ranking of the five treatment means is summarized here. AC BED Which of the statements below are true? Let "=" mean no statistically significant difference. Mean A < Mean B Mean E < Mean D Mean A - Mean C Mean A < Mean C Mean B= Mean C Mean B< Mean D Mean E< Mean D Mean B < Mean C O.
You may need to use the appropriate appendix table or technology to answer this question. Consider the following hypothesis test. H3: H1- Hz> 0 The following results are for two independent samples taken from the two populations. Sample 1 Sample 2 n, = 40 n2 = 50 = 25.1 X2 = 22.8 01 = 5.9 02 = 6 (a) What is the value of the test statistic? (Round your answer to two decimal places.) (b) What is the p-value? (Round your answer to four decimal places.)
Suppose you needed to test the claim that the two samples described below come from populations with the same mean. Assume that the samples are independent simple random samples. Sample 1: n1 13, a1 = 24, 81 = 7.55 Sample 2: n2 = 3, x2 = 21.9, 82 = 8.92 Find: (a) The estimated degree of freedom is (b) The standardized test statistic is (use Sample 1 - Sample 2)

You are conducting a study to see if the probability of catching the flu this year is significantly more than 0.2. You use a significance level of a = 0.005. Họ:p = 0.2 H1:p > 0.2 You obtain a sample of size n = 542 in which there are 126 successes. What is the test statistic for this sample? (Report answer accurate to three decimal places.) test statistic = What is the p-value for this sample? (Report answer accurate to four decimal places.) p-value = The p-value is.. less than (or equal to) a greater than a This test statistic leads to a decision to... reject the null accept the null fail to reject the null As such, the final conclusion is that. There is sufficient evidence to warrant rejection of the claim that the probability of catching the flu this year is more than 0.2. There is not sufficient evidence to warrant rejection of the claim that the probability of catching the flu this year is more than 0.2. The sample data support the claim that the probability of catching the flu…
